Panasonic FC series caps. 680uF 63v is available in 12.5mm diameter (35 mm tall!) size. Rated to 105C, they're only $1.35 at Digikey. I've got four of their 820uF/63v caps on my furnace board. It's like a 3 second UPS :-) _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
